A new beta release of pip, 20.2b1 has been released! You can install it by running
python -m pip install --upgrade --pre pip.
This release is mainly intended for users interested in testing the new resolver code (available via the
--unstable-feaure=resolver option to pip). Apart from the resolver, there are only a couple of changes over the current stable (20.1.1) release of pip. However, as we move closer to having a feature-complete release of the new resolver, we wanted to provide an updated snapshot of the new resolver functionality, to allow people interested in helping us with the testing to get access to the latest changes that have been made.
Thanks to everyone who has contributed to this release, and in particular to all of the people who have tested and provided feedback on the new resolver so far!
